XML驗證缺失標記

Question

這些XML驗證結果實際上代表什麼？

「nbres：/org/netbeans/modules/j2ee/ddloaders/catalog/resources/datatypes.dtd」中的引用實體。 cvc-complex-type.2.4.a：找到以元素「filter-name」開頭的無效內容。 「{」http://java.sun.com/xml/ns/javaee":description，「http://java.sun.com/xml/ns/javaee":display-name」，http：/ /java.sun.com/xml/ns/javaee":icon，「http://java.sun.com/xml/ns/javaee":servlet-name}」。 [48] 元素類型「servlet」必須由匹配的結束標記「」終止。 [50] XML驗證已完成。

我不太熟悉這些！

Answer 1

你手工編寫該XML？

錯誤消息將告訴您XML根據該公司預計，該架構是無效的：

1. 如果你有<filter-name>它期待的<description>之一，<display-name>，<icon>或<servlet-name>。
2. 你</servlet>標籤（或可能打開<servlet>）似乎是在錯誤的地方

編輯：我裝了XML的氧氣，它看起來像<servlet>的問題實際上是由於<filter>標籤剛過它是錯位的。

Answer 2

今天我遇到了類似的錯誤。我的代碼如下所示：

<servlet> 
    <init-param> 
     <param-name>data1</param-name> 
     <param-value>value1</param-value> 
    </init-param> 
    <init-param> 
     <param-name>data2</param-name> 
     <param-value>value2</param-value> 
    </init-param> 
    <servlet-name>ServletConfigServlet</servlet-name> 
    <servlet-class>com.netease.server.example.web.controller.ServletConfigServlet</servlet-class> 
</servlet> 

錯誤警告：

cvc-complex-type.2.4.a: Invalid content was found starting with element 'init-param'. 
One of '{"http://java.sun.com/xml/ns/javaee":description, 
"http://java.sun.com/xml/ns/javaee":display-name, 
"http://java.sun.com/xml/ns/javaee":icon, 
"http://java.sun.com/xml/ns/javaee":servlet-name}' is expected. 

我已經嘗試了一些解決方案。最後，我用修好了，更改了訂單<init-param>和<servlet-name>, <servlet-class>。它看起來像：

<servlet> 
    <servlet-name>ServletConfigServlet</servlet-name> 
    <servlet-class>com.netease.server.example.web.controller.ServletConfigServlet</servlet-class> 
    <init-param> 
     <param-name>data1</param-name> 
     <param-value>value1</param-value> 
    </init-param> 
    <init-param> 
     <param-name>data2</param-name> 
     <param-value>value2</param-value> 
    </init-param> 
</servlet> 

希望這可以幫助別人。 ：D
